So my thoughts are to replace the radiator now before problems arise, do you all agree with this preventative strategy? If so, any brand preferences? I do tow, hence need the cooling capacity.
Thanks,

* is long, but very comprehensive regarding this problem
long term fix - difficult to recommend
but in the short term, transmission oil in the coolant is sometimes difficult to detect
better to check for coolant in the trans oil
sometimes this is tough to see on the dipstick
all depends on how serious the contamination is, if any
my recommendation, at least for now, is to do the by-pass, and while doing so, drain some trans oil into a container and take a good look at it
that will give you the opportunity to determine if a problem exists, and be doing a preventative measure to avoid it until you decide on the proper long-term solution
i too would like to replace the radiator, or add an additional cooler and/or fan, but have not decided which way to go
but, at least there's no worry about transmission failure due to coolant contamination until then
